The print edition is published as 2 hardback volumes, parts A and B, and sold as a set. The Carboniferous was the time of the assembly of Pangaea by the collision of the Gondwanan and Larussian supercontinents, and the principal interval of the late Paleozoic ice ages. These tectonic and climatic events caused dramatic sea-level fluctuations and climate changes and produced a Carboniferous world that was diverse topographically and climatologically, perhaps only rivalled in that diversity by the late Cenozoic world. Furthermore, the Carboniferous was a time of the accumulation of vast coal deposits of great economic and societal significance. The temporal ordering of geological and biotic events during Carboniferous time thus is critical to the interpretation of some unique and pivotal events in Earth history. This temporal ordering is based on the Carboniferous timescale, which has been developed and refined for nearly two centuries. This book reviews the history of the development of the Carboniferous chronostratigraphic scale and includes comprehensive analyses of Carboniferous radioisotopic ages, magnetostratigraphy, isotope-based correlations, cyclostratigraphy and timescale-relevant marine and non-marine biostratigraphy and biochronology.

The Late Pennsylvanian was a time of ice ages and associated climate dynamics. A major reduction in Gondwana ice-volume was followed by a prolonged period of relative global warmth, culminating in the last great ice age of the late Paleozoic. It also was a major turning point in the evolution of life on land, when the coal forests of the Middle Pennsylvanian gave way to new kinds of Late Pennsylvanian wetland vegetation, and new kinds of animals appeared. Changes in the terrestrial biota began during the Middle Pennsylvanian, accelerating and proceeding in a spatially complex manner throughout the Late Pennsylvanian. The Late Pennsylvanian is thus a laboratory for studying environmental changes in a glacial world, and for assessing coeval biotic changes, in part to establish the possible links between the two. No book has been dedicated to this time interval, so this volume fills a gap in our understanding of a dynamic Late Pennsylvanian world that is much like the late Cenozoic world.
